This book highlights the most prominent research on the Popigai meteorite crater (Siberia, Russia), the 6th largest known impact structure in the world. Not only does the crater have a diameter of roughly 100 km, it is also an estimated 35.7 million years old. This monograph is an updated, extended and revised edition of the Russian-language book “Diamond-bearing Impactites of Popigai Astrobleme” and presents the most comprehensive research on the Popigai impact structure. The Popigai crater is unique in that the total amount of impact diamonds it contains exceeds all the other diamond-bearing provinces of the world. The work presented here is based on the geological mapping, core logging, geophysical survey and petrological studies of the crater, and was written by the team of geologists who first described the Popigai impact structure and its diamonds, and took part in the exploration of their deposits from 1970 to 1985.
This book presents essential data on the geology of the Puchezh-Katunki crater – an early Jurassic crater located on the East European Platform, with an impact structure that is ca. 80 km in diameter. Offering a comprehensive guide, it reviews the studies carried out during the last several decades on this prominent but not well-known impact structure. It offers the international community state-of-the-art information on the crater with regard to e.g. structural mapping, drilling (including the Vorotilovo well, which is 5374 m deep), geophysical research, and the petrological analysis of impactites and various breccias. In addition, the book includes new results from the mineralization and crystallizations beneath this large impact crater, and suggests new models for crater formations.
A collection of international contributions presenting current knowledge of impact tectonics, geological and geophysical investigations of terrestrial impact structures, and suggested new impact structures, resulting from the IMPACT program.
Defects in Solids, Volume 15: Etching of Crystals: Theory, Experiment, and Application focuses on the processes, reactions, and methodologies involved in the etching of crystals, including thermodynamics and diffusion. The publication first underscores the defects in crystals, detection of defects, and growth and dissolution of crystals. Discussions focus on thermodynamic theories, nature of pit sites, surface roughening during diffusion-controlled dissolution, growth controlled by simultaneous mass transfer and surface reactions, and chemical and thermal etching. The text then examines the theories of dissolution and etch-pit formation and the chemical aspects of the dissolution process, including catalytic reactions, dissolution of semiconductors, topochemical adsorption theories, and diffusion theories. The book tackles the solubility of crystals and complexes in solution and the kinetics and mechanism of dissolution. Topics include metallic crystals, semiconductors, stability of complexes, relationship between solubility, surface energy, and hardness of crystals, and solvents for crystals and estimation of crystal solubility in solvents other than water. The publication is a dependable source of data for readers interested in the etching of crystals.
Diamond is the record-setter in many mineralogical properties such as hardness, diffusivity, thermal conductivity, purity, and covalency of bonding. Similarly, diamond, as the premier gemstone of the mantle holds primacy for geological features such as age and depth of origin. Diamond was among the first crystalline structures to be solved by X-ray diffraction and the first materials measured for their Raman spectrum. At more than 80 billion USD in yearly commercial value, diamond sets the record for the most traded, valuable mineral on the planet. Despite its chemical simplicity, diamond has been the object of more research effort, and had more scientific and popular press pages written about it, than any other mineral.
The present volume is the result of activities within the scientific programme "Response of the Earth System to Impact Processes" (IMP ACT) of the European Science Foundation (ESF). The ESF is an association of 67 national member organisations devoted to scientific research in 24 European countries. The IMPACT programme is aimed at understanding meteorite impact processes and their effects on the Earth System. Launched in 1998 for a duration of 5 years, the programme is now supported by 15 ESF membership countries. The programme of meteorite impact research and operates through deals with all aspects workshops, exchange programs, and short courses. The 4th IMPACT programme workshop "Meteorite Impacts in Precambrian Shields" took place on May 24-28, 2000, in Lappajarvi, western Finland. A total of 84 scientists from 19 countries from Europe, North America, and Africa participated in the workshop. During the workshop, 43 oral, 31 poster, and several video presentations were made. An exhibition of impactite rocks from Finnish craters and two excursions were organised. The excursion to impact melt rock outcrops of the Lappajarvi structure took place during the workshop. The Karikkoselka and Saaksjarvi impact structures in south-central Finland were visited during the post-meeting excursion.
Diamonds in Nature: A Guide to Rough Diamonds illustrates the range of crystal shapes, colours, surface textures, and mineral inclusions of rough, uncut, naturally forming diamonds. Each chapter contains photographs that show the unique physical characteristics of the diamonds, and the accompanying text describes the processes that led to their formation. This book is an invaluable reference manual for professional geoscientists—including gemmologists and exploration geologists.
This volume of Advanced Mineralogy encompasses six different areas having two features in common: they are related to one of the largest enterprises of the second half of this century; and represent the ultimate and final extension of the concept of mineral matter. - Understanding mineral matter in Space is one of the principal purposes of cosmic exploration. This includes the results of compa rative planetology, lunar epopee, sophisticated meteorite studies (now more than 500 meteorite minerals), discovery of the interstellar mineral dust forming some 60 trillion of earth masses in the Galaxy, and terrestrial impact crater studies. It is possible now to speak of mineralogy of the Universum, and the mineralogical type of the states of matter in the Universe. Direct samples of mantle xenoliths and ultrahigh pressure-tem perature experiments make it possible to consider the mineral ogical composition of the Earth as a whole, including the upper an lower mantle and the Earth's core. Deep ocean drilling programs, a scientific fleet of hundreds of vessels and several submersibles have brought about great dis coveries in the geology, metalogeny, and mineralogy of the ocean floor the largest part of the Earth's surface, in particular revealing new genetic, crystallochemical, and ore types of min eral formation.
"The third volume of the series “Large Meteorite Impacts” provides an updated and comprehensive overview of modern impact crater research. In 26 chapters, more than 90 authors from Europe, the United States, Russia, Canada, and South Africa give a balanced, firsthand account of the multidisciplinary field of cratering science, with reports on field studies, geophysical analyses, and experimental and numerical simulations. Nine chapters focus on structure, geophysics, and cratering motions of terrestrial craters. Recent advances in impact ejecta studies and shock metamorphism are assembled, each with seven chapters, and three chapters extend the scope from a terrestrial to a planetary perspective."--pub. desc.
